TSA Faces Lawsuit Over Little-Known Rule

Most frequent flyers are aware of the common rules for the Transportation Security Administration (TSA), like the rules limiting the amount of liquid that can be taken in carry-on luggage and the rules limiting weapons and sharp objects. However, there is one lesser-known rule that is currently facing a legal challenge.

While federal law requires those traveling in or out of the United States with currency exceeding $10,000 to report it to U.S. Customs and Border Protection, no such limitation exists for domestic flights.
